WebAt a trench, one tectonic plate (the “downgoing plate”) plunges beneath another (the “overriding plate”) at what is called a “subduction zone.” The downgoing plate bends and angles downward into the Earth’s mantle, and the boundary between the two plates develops into a trench (Figure 1). WebJul 8, 2024 · Answer: Divergent boundaries -- where new crust is generated as the plates pull away from each other. Convergent boundaries -- where crust is destroyed as one plate dives under another. Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other. Advertisement Advertisement

WebThere are fifteen principal plates distinguished (Figure 2): Eurasian, African, Arabian, Indian, Australian, Antarctic, North American, Caribbean, South American, Scotia, Nazca, Cocos, Juan de Fuca, Philippine, and Pacific. There are also several smaller plates, or “microplates,” whose independence from large plates is limited, however. WebThree main types of plate boundaries: Divergent: extensional; the plates move apart. Spreading ridges, basin-range. Convergent: compressional; plates move toward each other.
